Título: | Spin entanglement loss by local correlation transfer to the momentum |

Fecha de publicación: | 31-may-2006 | Editor: | American Physical Society | Citación: | Physical Review A 73(5): 052325 (2006) | Resumen: | We show the decrease of spin-spin entanglement between two s= 1/2 fermions or two photons due to local transfer of correlations from the spin to the momentum degree of freedom of one of the two particles. We explicitly show how this phenomenon operates in the case where one of the two fermions (photons) passes through a local homogeneous magnetic field (optically active medium), losing its spin correlations with the other particle. | Descripción: | 7 pages, 7 figures.-- PACS nrs.: 03.67.Mn, 03.65.Yz, 03.65.Ud.-- ArXiv pre-print available at: http://arxiv.org/abs/quant-ph/0603225 | Versión del editor: | http://dx.doi.org/10.1103/PhysRevA.73.052325 | URI: | http://hdl.handle.net/10261/12378 | DOI: | 10.1103/PhysRevA.73.052325 | ISSN: | 1050-2947 |
